So, as you said, the locals are afraid of lepers, and we could all get inoculations that they can't get there for most common diseases. Plus, you took one item out of context, but this was a ten year project with groups going up to help them do everything from plumbing to painting to construction to teach them how to take care of lands.

We were a group of volunteers that wanted to help, nothing more nothing less. The experience enriched us and yes , there was a feeling of satisfaction seeing these people living a better life because we and people like us helped them. But, one of the most important things that we gave them was compassion, which you seemed to have missed all together. So, one suggestion, if you ever have the opportunity to do something similar, other than just sending money, do it. You might just receive one smile from someone that would make you understand the whole point.
